Problem to compile objects

[Matiasdt]

We recently migrated the Oracle database from 9i to 11g. I am presented with the situation that when compiling a package with version 12.01.1814 it is invalid but if I compile it with version 11.01.1765 it is compiled. for what is this? Thank you

How exactly is it invalid? Any error messages or compilation errors?

 

[Matiasdt]

Thank you Marco.
For example an error is as follows:

Compile Errors in the PACKAGE object TRON2000.GC_K_CBOS_LILEN_MAPFRENET_MAR.

Error: PLS-05018: The GC_K_CBOS_LILEN_MAPFRENET_MAR unit has omitted the optional AUTHID clause; The default value DEFINER has been used
Line: 1
Text: CREATE OR REPLACE PACKAGE TRON2000.gc_k_cbos_lilen_mapfrenet_mar

Looks like a compiler warning, which you can either ignore or else configure in Preferences > Compiler. Are you sure it's PLS-05018 and not PLW-05018? Is the package in an invalid state?
